FOXO1 and urinary bladder neoplasm: Immunohistochemical staining in TUR specimens further demonstrated that the rates of FOXO1/phospho-FOXO1 positivity were significantly (both p < 0.001) lower and higher, respectively, in bladder tumors (13%/57%) than in normal-appearing urothelial tissues (40%/24%) and that FOXO1 positivity, as an independent predictor (hazard ratio 0.128, p = 0.043), was associated with a higher risk of postoperative recurrence of non-muscle-invasive tumors.
